The primar object of the present invention'is to pro uce apintleless pin having a pin-tongue that may readily be assembled with the front plate or back plate, as the case may be, and easily replaced by another in case it becomes damaged. v

In the drawings accompanying and forming a part of this specification-.

Figure 1 is a longitudinal section of a front rplate or back plate of a pin in one stage of its construction Fig. 2 is a plan view showing the completed plate; a

Fig. 3 is a longitudinal section of the com- 3n pleted pin; N

Fig. 4 is a side view of the pin-point catch;

Fig. 5 is a section on the line 55 of Fig. 3;

Fig. 6 is a longitudinal section of a modi- 57C) fication; V

Fig. 7 is a transverse section on the line 7-7 of Fig. 6; Fig. 8 is a transverse section of the spring clip; and

Fig. 9 is a side view of said clip. In the particular drawings selected for more fully disclosing my invention, and which are to be taken as illustrative merely, and not as restrictive, 10 represents a metallic shell which may be used either as a front plate, or as a back plate, in which case an ornamental front plate, enamelled or otherwise,willbesoldered thereto. One end of said shell terminates in the catch 11 for the pin point, and the other in the up-turned housing 12 for the bent portions of the pin-tongue 13, which is made of spring material bent upon itself and comprising an upper and lower arm. The sides of theshell 10 are slotted at 14, leaving oppositely-disposed tongues 15, and near the other end the sides of said shell are provided with a pair of lugs 16. The two tongues are then reversely bent, as shown in Fig. 2, to form a spring lock through which the bent portion 16 of the'pin-tongue is slipped, the upturned end 17 of the lower arm of said pin-tongue being housed within the catch 11, but is relatively movable there- In case the pin-tongue becomes damaged, it

may readily be removed-by spreading the tongues 15 and drawing the same through the opening therebetween.

In the modification shown in Fig.6, two lnwardly-directed lugs 19 are formed on the walls of the .plate 10, and are constructed and arranged to cooperate with the spring clip 20 having two substantially parallel side pleces provided with perforations 21 having the same inclination as the lugs 19. The two parallel side pieces of the spring clip are connected by an inclined top-piece 22, the central portion 23 of which is deeply grooved and inclined with respect to the base of the plate 10 so that when thepin is closed, the portion thereof adjacent to the bent end will lie with- 1n said groove.

To assemble the pin, the pin-tongue is placed 1n position in the plate and the spring clip 1s snapped onto the lugs 19. In case the pin-tongue becomes damaged, it may readily be removed by compressing the sides of the spring clip, and then removing the same, whereupon the damaged pin-tongue is taken outand replaced by another, after which said spring clip is again snapped in position.

As will be readily apparent, the locking device at thehinge end of the pin shown in F g.3 may be used with the catch shown in Fig. 6, and the lockin device shownin Fig. 6 may be used with t e catch illustrated in Flg. 3.

It will be noted that in both forms of the present invention, the bent portion of' the pin-tongue is flexibly secured to the plate at the end opposite the pin-point-retaining means, and the free end of the lower arm is also flexibly secured to said plate.

Having thus described illustrative embodiments of my invention without, however, limiting the same thereto, what I claim and desire to secure by Letters Patent is I 1 -A pin having a plate, a pin-tongue of sprlng material bent upon itself and comprislng an upper and a lower arm, pin-point-retaming means at one end of said plate, and resilient means at the other end of said plate for rgmovably securing said pin-tongue to said p ate..
